Hi Michael,

Add basic support for the Kontron SMARC-sAL28 board. This includes just the bare minimum to be able to bring up the board and boot linux.
For now, the Single and Dual PHY variant is supported. Other variants will fall back to the basic variant.
In particular, there is no watchdog support for now. This means that you have to disable the default watchdog, otherwise you'll end up in the recovery bootloader. See the board README for details.

After applying the patch (https://patchwork.ozlabs.org/project/uboot/patch/20200803221633.24096-1-mich...) I could boot the mainline kernel.

+Summary +=======
+The Kontron SMARC-sAL28 board is a TSN-enabled dual-core ARM A72 +processor module with an on-chip 6-port TSN switch and a 3D GPU.
+Quickstart +==========
+Compile U-Boot +--------------
+Configure and compile the binary::
- $ make kontron_sl28_defconfig
- $ CROSS_COMPILE=aarch64-linux-gnu make
Small typo here. A missing '-'. $ CROSS_COMPILE=aarch64-linux-gnu- make
+Copy u-boot.rom to a TFTP server.
+Install the bootloader on the board +-----------------------------------
+Please note, this bootloader doesn't support the builtin watchdog (yet), +therefore you have to disable it, see below. Otherwise you'll end up in +the failsafe bootloader on every reset::
+The board is fully failsafe, you can't break anything. But because you've +disabled the builtin watchdog you might have to manually enter failsafe +mode by asserting the ``FORCE_RECOV#`` line during board reset.
+Disable the builtin watchdog +----------------------------
+- boot into the failsafe bootloader, either by asserting the
- ``FORCE_RECOV#`` line or if you still have the original bootloader
- installed you can use the command::
+- in the failsafe bootloader use the "sl28 nvm" command to disable
- the automatic start of the builtin watchdog::
+- power-cycle the board
+Useful I2C tricks +=================
+The board has a board management controller which is not supported in +u-boot (yet). But you can use the i2c command to access it.
+- reset into failsafe bootloader::
+- read board management controller version::
+Non-volatile Board Configuration Bits +=====================================
+The board has 16 configuration bits which are stored in the CPLD and are +non-volatile. These can be changed by the `sl28 nvm` command.
+=== =============================================================== +Bit Description +=== ===============================================================
- 0 Power-on inhibit
- 1 Enable eMMC boot
- 2 Enable watchdog by default
- 3 Disable failsafe watchdog by default
- 4 Clock generator selection bit 0
- 5 Clock generator selection bit 1
- 6 Disable CPU SerDes clock #2 and PCIe-A clock output
- 7 Disable PCIe-B and PCIe-C clock output
- 8 Keep onboard PHYs in reset
- 9 Keep USB hub in reset
- 10 Keep eDP-to-LVDS converter in reset
- 11 Enable I2C stuck recovery on I2C PM and I2C GP busses
- 12 Enable automatic onboard PHY H/W reset
- 13 reserved
- 14 Used by the RCW to determine boot source
- 15 Used by the RCW to determine boot source
+=== ===============================================================
+Please note, that if the board is in failsafe mode, the bits will have the +factory defaults, ie. all bits are off.
+Power-On Inhibit +----------------
+If this is set, the board doesn't automatically turn on when power is +applied. Instead, the user has to either toggle the ``PWR_BTN#`` line or +use any other wake-up source such as RTC alarm or Wake-on-LAN.
+eMMC Boot +---------
+If this is set, the RCW will be fetched from the on-board eMMC at offset +1MiB. For further details, have a look at the `Reset Configuration Word +Documentation`_.
+Watchdog +--------
+By default, the CPLD watchdog is enabled in failsafe mode. Using bits 2 and +3, the user can change its mode or disable it altogether.
+===== ===== =============================== +Bit 2 Bit 3 Description +===== ===== ===============================
- 0 0 Watchdog enabled, failsafe mode
- 0 1 Watchdog disabled
- 1 0 Watchdog enabled, failsafe mode
- 1 1 Watchdog enabled, normal mode
+===== ===== ===============================
+Clock Generator Select +----------------------
+The board is prepared to supply different SerDes clock speeds. But for now, +only setting 0 is supported, otherwise the CPU will hang because the PLL +will not lock.
+Clock Output Disable And Keep Devices In Reset +----------------------------------------------
+To safe power, the user might disable different devices and clock output of +the board. It is not supported to disable the "CPU SerDes clock #2" for +now, otherwise the CPU will hang because the PLL will not lock.
+Automatic reset of the onboard PHYs +-----------------------------------
+By default, there is no hardware reset of the onboard PHY. This is because +for Wake-on-LAN, some registers have to retain their values. If you don't +use the WOL feature and a soft reset of the PHY is not enough you can +enable the hardware reset. The onboard PHY hardware reset follows the +power-on reset.
